So, in Anonyms (I) they are teaching antonyms which is an antonym of anonym. I take it the teacher was unable to determine either that or the issue of the words in the box not matching really as anonyms or as antonyms. I’ve seen most of the teachers my children had while in public school also unable to comprehend such things (even when it was shown to them) which is, in part, why homeschooling is becoming so prevalent.
